Homework Help: Chemistry Acid/base solubility question

  1. Oct 11, 2012 #1
    1. The problem statement, all variables and given/known data


    Each of the following salts can be prepared from an acid and a base. Write the balanced molecular equation and the net ionic equation for the preperation of each. indicate states of the reactants and producys . Review solubility rules if neccesary to determine the solubility of reactants.

    2. Relevant equations



    3. The attempt at a solution

    a) AgNO3
    b)RbClO4
    C) Na3PO4

    a/ AgOH(s) + HNO3(aq) --> AgNO3(aq) + H2O(aq) (the molecular equation
    Net ionic: AgOH + H+ + NO3- ------> Ag+ + NO3- + H2O
    Final net ionic after cancellation: AgOH- + H+ ---> Ag+ + H2O

    Am I write on this first one? i dont really think I am, im not confident in it

    b/ RbClO4

    my attempt: RbOH(s) + HClO4- ----. RbClO4 (aq) + H2O

    My attempt at net ionic: RbOH(s) + H+ + ClO4- ---> Rb+ + H2O
    Final net ionic after cancellation: RbOH + H+ ---> Rb+ + H2O

    Is this right? Please help!!

    Close, but you need to pay attention to charges - no such thing as AgOH- (although you wrote it correctly in other places). Also, it won't hurt to mark the fact AgOH is insoluble.

    RbOH is well soluble (as opposed to AgOH) and 100% dissociated.
